Abstract: An improved IV infusion set of the type comprising a length of tube with a hollow needle at one end. The improvement comprises a sheath slidably disposed on the tube and adapted to be slid over the needle to cover the needle after use. The sheath is particularly adapted for use with IV infusion sets of the type comprising outwardly projecting flexible wings adjacent the end of the tubing with the needle, commonly referred to as "butterfly" infusion sets. The sheath comprises a hollow generally tubular body having a slot extending longitudinally from the forward end of the body partway toward the rearward end, and a cutout in the body at the rearward end of the slot. The slot allows the wings to pass to the cutout to allow at least a portion of the sheath to slide past the wings to cover the needle. The cutout engages the wings, locking the body in its position covering the needle.

Abstract: An improved syringe having a combined safety sheath and needle cap. The syringe is of the type comprising a barrel having a needle extending from the lower end. The sheath is slideably mounted on the barrel between a retracted position and an extended position, to visually indicate when the syringe has been used when the sheath is in the extended position, with means for locking the sheath in the extended position. A needle cap is provided for removal from the needle during use and for the possibility of recapping after use. The improved syringe further comprises a knob extending outwardly from the barrel near the lower end. The sheath has a slot for receiving the knob, the slot having tabs for releasably retaining the sheath in its retracted position releasable upon downward pressure applied to the sheath, and tabs for lockingly engaging the knob to lock the sheath in the extended position.

Abstract: A safety needle cap comprising a generally cylindrical, hollow tubular body section having a closed first end and an open second end for receiving the needle, and a funnel-shaped lip surrounding the open end and projecting radially and axially outwardly to channel needles into the open end and protect fingers gripping the cap. The cap further having a guard extending from the body section intermediate the two ends to intercept needles missing the funnel-shaped lip, and positioned to space the fingers away from the open end, out of danger. The guard may be flat and disk-shaped or it may be funnel-shaped, opening toward the open end to trap errant needles.
